Dozens of people have been injured in a wave of missile strikes on the Ukrainian capital Kyiv overnight, authorities say.
Fifty-three people were hurt in the attacks, including six children, Kyiv mayor Vitali Klitschko said.
Kindergarten and hospital buildings were reportedly damaged by debris as authorities said 10 Russian ballistic missiles had been shot down.
The strikes happened after President Volodymyr Zelensky left the US.
His plea for Congress to agree more military aid for Ukraine made little progress in winning over reluctant Republicans.
EU leaders will also discuss further aid for Ukraine on Thursday, and European Commission President Ursula von der Leyen said “we must give Ukraine what it needs to be strong today”.
On Wednesday, the EU said it would unblock €10bn in funding for Hungary, in a move criticised as an attempt to persuade Hungarian Prime Minister Viktor Orban to loosen his objections to helping Ukraine.
Mr Zelensky promised a response to Wednesday’s overnight attack. “Russia has proven once again that it is a heinous country that fires missiles at night, trying to hit residential areas, kindergartens, and energy facilities during the winter,” he posted on X.
Wednesday’s attack on Kyiv began at around 03:00 (01:00 GMT) – the third Russian missile strike on the capital in the past week.
